摘 要:目的调查珠江三角洲地区超低/极低出生体重儿(extremely/very low birth weight in—fants,ELBWI/VLBWI)出生时宫内发育迟缓(intrauterine growth retardation,IUGR)和出院时宫外发育迟缓(extrauterine growth retardation,EUGR)的发生率,为其出院后进行生长发育监测和干预提供依据。方法回顾性调查广东省珠江三角洲地区9个城市的9家医院新生儿科于2010年7月1日至2011年6月30日期间出院的ELBWI/VLBWI的住院资料,分别以出生时、出院时的体重在相应宫内生长速率期望值的第10百分位水平以下(生长曲线的第10百分位)定义为IUGR、EUGR,分别计算各胎龄组、各体重组、单胎与多胎组的IUGR、EUGR发生率,并计算各组EUGR较IUGR增加的发生率。生长曲线参照“Fenton生长曲线2003-胎儿、婴儿生长曲线(供早产儿参考)(WHO生长标准版)”。结果318例ELBWI/VLBWI出生时IUGR发生率为33.3%(106例),出院时EUGR发生率为70.8%(225例)。以出生胎龄(〈30周、〈32周、≥32周)进行分组统计,EUGR发生率分别为55.7%(68/122)、66.9%(79/113)、94.0%(79/83)(X^2=34.964,P=0.000),较IUGR发生率分别增加49.2%(60/122)、51.3%(58/113)、1.2%(1/83)(x。=63.024,P=0.000);以出生体重(≤1200g、≤1350g、〉1350g)进行分组统计,EUGR发生率分别为83.8%(88/105)、65.3%(66/101)、63.4%(71/112)(X^2=13.009,P=0.001),较IUGR发生率分别增加42.9%(45/105)、35.6%(36/101)、33.9%(38/112)(X^2=2.045,P=0.360);以单胎和多胎进行分组比较,则IUGR、EUGR及EUGR较IUGR增加的发生率,组间差异均无统计学意义(P〉0.05)。结论ELBWI/VLBWI出院时EUGR发生率仍然很高,出院时EUGR发生率随出生胎龄的增加或出生体重的降低而升高,且出院时EUGR较出生时IUGR�Objective To research the incidences of intrauterine growth retardation(IUGR) and ex-trauterine growth retardation (EUGR) of extremely and very low birth weight infants, which would be helpful to growth monitoring and therapeutic intervention after hospital discharge. Methods Clinical data of ex-tremely and very low birth weight preterm infants, who discharged from July lst,2010 to June 30th, 2011, were collected retrospectively from 9 neonatal intensive care units of 9 cities in Pearl River Delta, Guangdong province. The body weight at birth and on discharge of each infant was compared to the expected value based on the intrauterine growth data and postmenstrual day on discharge. Growth retardation was defined as meas- ured body weight ≤ 10 th percentile of the expected value. In each specific group,the number of infants with≤ 10 th percentile was counted and the percentages of patients who had values ≤ 10 th percentile at birth and on discharge were calculated. And the increasing incidence from IUGR to EUGR in each specific group was also calculated. The growth curve used for assessing body weight of different gestational age infants was Fetal-in-fant Growth Chart for Preterm Infants (WHO Growth Standards version). Results Three hundred and eighteen cases of extremely and very low birth weight infants were enrolled in this research. The incidence of IUGR was 33.3% (106/318) ,while the incidence of EUGR was 70. 8% (225/318). In each group divided by gestational age( 〈 30 week, 〈 32 week, ≥32 week) ,the incidence of EUGR were 55.7% (68/122), 66.9% (79/113 ) and 94. 0% ( 79/83 ) (X^2 = 34. 964, P = 0. 000 ), which increased by 49.2% ( 60/122 ), 51.3% (58/113) and 1.2% (1/83) from IUGR (X^2 =63. 024,P =0. 000). In each group divided by birth weight( ≤1200 g,≤1350 g, 〉 1350 g) ,the incidence of EUGR were 83.8% (88/105) ,65.3% (66/101) and 63.4% (71/112) (X^22 = 13.009 ,P =0. 001 ) ,which increased by 42. 9% (45/105) ,35
